Kenny,
I always use straight colour on any models because of that reason.
Have just finished the 1/48 accurate minatures Avenger (full photoetch too, arrrgh!) in RNZAF (Royal New Zealand Airforce) colours. I stuck religiously to the FS no.s and faded mainly using chalks and mig powders. With figures and model colour I'm learning how to vary the creases and folds on uniforms. This requires mixing. On some of the resource books I have they use set colours and ratios which are great but mainly concentrate on german camo. With allied uniform colours do you know of any titles???
In addition to the embarrassment of pink, I'm a New Zealander living in Australia. You can't imagine all the jokes !!!!!!!! If looking for something different to model have a look at the classic airframes 1/48 Vampire in RNZAF colours or just type into your search engine ANZAC or GALLIPOLLI. You maybe surprised.
Cheers,
Dave
